Question

3x +2y = 11
2х - у = -3
​

Answer 1

Answer:

x=5/7;y=31/7

Hope you understood

Answer 2

(x,y) = (5/7, 31/7)

Step-by-step explanation:

3x + 2y = 11 .... (1)

2x - y = -3 .... (2)

in equation (2),

2x - y = -3

→ -y = -3 -2x

→ y = 3 + 2x

substitute value of y in equation (1)

3x + 2(3+2x) = 11

→ 3x + 6 + 4x = 11

→ 7x = 11 - 6

→ 7x = 5

:. x = 5/7

substitute value of X in equation (2)

2(5/7) - y = -3

→10/7 - y = -3

→-y = -3 -10/7

→y = 3+ 10/7

→y = 31/7

therefore, solution of the equation is (x,y) = (5/7,31/7)
